The GOTECK GS-2502 digital micro servo is an ultra-lightweight, compact servo for small-scale RC aircraft, indoor flyers, micro drones, robotics projects and other lightweight precision-controlled applications.
It weighs just 2 grams and delivers 0.2kg.cm of torque at 6V, so it moves control surfaces without affecting the overall model weight. It runs between 4.5V and 6V and has a listed response speed of 0.08 seconds per 60 degrees.
Durable plastic gears, multiple servo horns and easy-to-install mounting hardware give hobbyists, educators and RC enthusiasts a versatile little servo.
Lightweight 2g design: ideal for micro models.
0.2kg.cm torque: at 6V.
Wide voltage range: 4.5V to 6V.
Fast response: 0.08 seconds per 60 degrees at 6V.
Multiple servo horns: included for different linkages.
Easy installation: with mounting hardware.
Durable construction: plastic gear train.
A hobby servo combines a small motor, a gearbox and a position sensor with control electronics. You send it a pulse every 20 milliseconds or so, and the width of the pulse tells it where to go: about 1.5 milliseconds is centre, with roughly 1.0 and 2.0 milliseconds at the ends. The servo drives its output shaft until the sensor says it has reached the commanded position, then holds it against the load.
Digital servos process the signal with a microcontroller and drive the motor at a much higher rate than analogue servos, which gives faster response, a smaller dead band and stronger holding torque. Metal gears cope better with shock loads than plastic ones, and ball bearings keep the shaft smooth and reduce wear.
Always power a servo from a supply that can deliver its peak current, not from a weak receiver port, and keep the linkage free so the servo never strains against a mechanical stop. A stalled servo draws a large current and can overheat within seconds.

The specification list gives the brand as DYS, a size of 16.0 x 8.0 x 20.0mm, a torque of 0.2kg per 0.09 seconds at 6V, a weight of 2.2g and a speed of 0.11 to 0.09 seconds per 60 degrees. The description quotes 0.08 sec/60 at 6V, so treat the speed as around 0.08 to 0.11 seconds depending on voltage.
The package includes the GS-2502 servo and an accessory kit. Plastic gears are best for light loads, so use it only where the forces are small.
